The RAIN scale: A good intention that falls short
Radiation protection specialists agree that clear communication of radiation risks remains a vexing challenge that cannot be solved solely by finding new ways to convey technical information.
Earlier this year, an article in Nuclear News described a new radiation risk communication tool, known as the Radiation Index, or, RAIN (“Let it RAIN: A new approach to radiation communication,” NN, Jan. 2025, p. 36). The authors of the article created the RAIN scale to improve radiation risk communication to the general public who are not well-versed in important aspects of radiation exposures, including radiation dose quantities, units, and values; associated health consequences; and the benefits derived from radiation exposures.

Expected errors in reactivity measurements made with a servo control are discussed and compared with observation. The influence upon measurement statistics of a residual spurious reactivity drift, of variable detector efficiency, and of servo control parameters is examined and compared with results using a thermal reactor at 72 watts. Power limited precision is shown to be obtainable with a servo control over a broad range of operating configurations and with good discrimination against incoherent residual reactivity drift.
